MeshTopology

Trait MeshTopology 

pub trait MeshTopology {
    // Required methods
    fn topological_dimension(&self) -> usize;
    fn entity_count(&self, dimension: usize) -> Option<usize>;
    fn incidence(
        &self,
        entity: MeshEntity,
        target_dimension: usize,
    ) -> Option<Vec<EntityIncidence>>;
}
Description

Arbitrary-dimensional topology contract.

Entities are stratified by topological dimension. incidence works in either direction, so cell closures and facet-to-cell adjacency share one operation instead of separate dimension-specific APIs.

Required Methods§

fn topological_dimension(&self) -> usize

Topological mesh dimension.

fn entity_count(&self, dimension: usize) -> Option<usize>

Entity count in a valid dimension stratum.

fn incidence( &self, entity: MeshEntity, target_dimension: usize, ) -> Option<Vec<EntityIncidence>>

Oriented entities of target_dimension incident to entity in deterministic reference-cell order. Invalid IDs or dimensions return None.
